AnduinOS is a Linux distribution created by a former Microsoft engineer, designed to ease the transition from Windows to Linux. It is based on Ubuntu and offers two versions: a Long-Term Support (LTS) release and a short-term release that showcases the latest features. AnduinOS shifts from Snap packages to the Flatpak system for better application access and package management. The interface closely resembles Windows 11, featuring a desktop environment with a taskbar that combines a dock and status bar, a Start menu designed for smoother performance, and customization options for the taskbar and Arc menu. It utilizes GNOME extensions to enhance functionality, including an Extension Manager for easy installation of new features. AnduinOS is positioned as a suitable option for users transitioning from Windows due to its familiar interface and extensive customization capabilities.
